y = -5(x+3)
0 = -5x-15
5x = -15
x = -3 (x-intercept occurs at (-3,0))
y = 0-15
y = -15 (y-intercept occurs at (0, -15))
y-intercept: 2 x-intercept: 4
Not quite. 'm' is the slope of the line. 'b' is the y-intercept The x-intercept is ( -b/m ).
The function y = -1 has no x-intercept; its graph is a horizontal line with a y-intercept of -1.
-1/2
Call the intercept with the y-axis b. The equation for the line is then y=5x+b With the information about the x-intercept we get: 0=5*7+b b=-35
